Isn’t tloc-extension specifically for transport to transport links? That points to D.

Maybe C. The tloc-extension typically pairs a service interface with a transport one, so D’s transport-to-transport binding doesn’t fit the usual pattern. That rules out options A and D for me.

It’s D because the tloc-extension command actually creates a binding between two transport-type interfaces. Since both sides are transport, options A and C are invalid. Option B mixes transport and service, which tloc-extension doesn’t do. This matches the documentation where tloc-extension extends the transport locator info, so binding happens transport to transport. The config snippet confirms ge 0/2.101 and ge 0/0 are both transport-type here, making D the right choice.

It’s C for sure. The key part is that tloc-extension always links a service interface to a transport interface, never transport to transport or service to service. So options A and D are out right away. Between B and C, the example config clearly shows ge 0/2.101 as service and ge 0/0 as transport, matching option C exactly. That fits the documentation too, so no doubt about it.

Option C makes sense since tloc-extension connects a service interface to a transport interface, not transport to transport or service to service, which rules out D and A.

Not A, because the command links service to transport interfaces, not service to service.

C - It links service on one end to transport on the other.
